Causes

In some people, it may be caused by the normal aging process. In others, it may be caused by trauma from:

• A fall on an outstretched hand
• A pull on an arm, such as from losing grip of something that is heavy
• A direct blow to the shoulder
• A dislocated shoulder
• A motor vehicle accident
• Repetitive overhead activities, such as sports that involve throwing

Risk Factors

This problem is more common in men. Other things that may raise your risk are:

• Playing some sports, such as baseball (pitchers), golf, weightlifting, and tennis
• Lifting heavy objects
• Having a health problem that may result in falls, such as weak muscles

Symptoms

Problems may be:

• Shoulder or arm pain
• Pain that is worse with shoulder movement
• A painful clicking or popping feeling in the shoulder
• Catching or loosening feeling in the shoulder
• Weakness of the shoulder or arm

Diagnosis

You will be asked about your symptoms and health history. You will also be asked how the injury happened. A physical exam will be done. It will focus on the shoulder and arm. You may need to see a doctor who treats bones.

Images will be taken of the shoulder. This can be done with an x-ray. An MRI scan may also be done.

Treatment

It will take 4 to 6 weeks for most people to heal. The goals of treatment are to manage pain and support the shoulder as it heals. This may include:

• Medicine to ease pain and swelling
• A sling to keep the shoulder in place as it heals
• Exercises to help with strength and range of motion

Some people may need surgery when other methods do not help. This can be done with shoulder arthroscopy. A thin, lighted tube is inserted through a small incision in the shoulder. Small instruments are also passed through the opening. The torn ligament or tissue is removed or sewn together. Wires or tacks may be used to reattach any torn tendons.

Prevention

Doing stretching and strengthening exercises that target the shoulder can help lower the risk of this injury.
